During a given week a programmer spend 1/4 of his time preparing charts, 3/8 of his time for coding, rest of his time for debugging the programs. If he had 48hrs during the week . How many hours did he spend debugging the program?

18hrs

prodam: 18hrs

GBAM!! Is this programming math?

1/4 + 3/8 = 5/8

so 5/8 hours was spent codin and drawing up charts.

now the rest of the time used will be=

1/1 - 5/8 =3/8

so 3/8 of 48 hours will be
3/8 * 48 = 18hours

Time spent on coding and charts: 1/4 + 3/8 = 5/8 of 48hours = 30hours....
Time spent on debugging: 48 - 30 = 18hours

First
NO ONE needs to spend 1/4 time on charts!!
For crying out loud netbeans 6 can generate UML diagrams, plus we got Balsamiq Mockup, Visual-Paradigm, Gliffy, Creately, YUML, LucidChart, MSWOrd, and tons of apps out there to make charting a breeze!!! If you know what you want, Charts and the slides needed for presentation shouldn't waste time!!
Second
Debugging time can be reduced to near zero by adopting good programming principle and testing as you code.
Third
Yea testing takes the bulk of the time but even that has been reduced somewhat since automated testing became the craze...

With that said, many seem to find Programming straight forward at first and thinking it don't need a big deal of math...
Well that's only before you begin PDS - PROGRAMMING DATA STRUCTURES!! Even cool languages like Java where you have tons of classes pre-written for data structures like ArrayList, HashMap, etc., try BINARY SEARCH TREE, try RECURSION!!!
MATH, and not just basic algebra, is a crucial bit in C/C++ and Game Development!
It all lies in how well we can understand PDS...
